Hmm, this demonstrates some of our headers may only be included when
certain CONFIG_* are defined.

Actually, I ran into a related case myself: headers that don't compile
with CONFIG_WIN32.

We can either add suitable ifdeffery to make our headers work always, or
mark headers so the test skips them when their requirements aren't met,
similarly to how this patch skips certain headers when CONFIG_WIN32 is

Regardless, we need to find the problemtatic headers.  Perhaps you can
find a few more with "make -k check-source".
